Sustech Ag
Sustech Ag is a Private limited company (Ltd.) registered in Switzerland under CHE114038251, and its current status with Zefix — Swiss Central Business Names Index is active. Its registered address on file is Uster, Switzerland. 1 shareholder is on record for Sustech Ag, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Zefix — Swiss Central Business Names Index and was last updated on 5 October 2026.
